RAID Levels Supported by PERC H755N

The flexibility of the PERC H755N allows it to support various RAID levels, offering businesses the ability to configure their storage arrays to meet specific needs. These RAID levels include:

• RAID 0: Provides striping across multiple drives for maximum performance but no redundancy. Ideal for applications requiring fast data access and minimal fault tolerance.
• RAID 1: Offers mirroring, ensuring data redundancy by duplicating data across two drives. This provides fault tolerance, enhancing data reliability without compromising performance.
• RAID 5: Combines data striping with parity, offering both redundancy and enhanced performance. It requires at least three drives and is ideal for applications with large datasets.
• RAID 6: Similar to RAID 5 but with double parity, allowing the controller to survive the failure of two drives. RAID 6 is excellent for high-reliability environments requiring additional fault tolerance.
• RAID 10: Combines RAID 1 and RAID 0, offering both performance and redundancy. It provides high throughput and excellent fault tolerance, making it ideal for critical applications.
• RAID 50: A combination of RAID 5 and RAID 0, offering the redundancy of RAID 5 with the performance boost of RAID 0, suited for demanding applications requiring both speed and fault tolerance.

Advanced RAID Features for Enhanced Data Integrity

The PERC H755N features advanced RAID management tools that ensure data integrity across all configurations. With features like data scrubbing, which proactively checks for inconsistencies, and background initialization, which rebuilds arrays without affecting system performance, the controller minimizes the risk of data corruption and optimizes array health.

Hardware and Software Compatibility

The PERC H755N PCI-E controller is designed to integrate smoothly with a variety of hardware and software environments, ensuring compatibility across different platforms and operating systems.
